adidas Women's Ultraboost 1.0 Sustain Running Shoes

Our review of the adidas Women's Ultraboost 1.0 Sustain finds a running shoe aimed at runners and daily wearers who prioritize a springy, comfortable ride and sustainable materials. The single biggest reason to buy is the exceptional energy return from the adidas BOOST midsole, which delivers a noticeably responsive feel that helps keep momentum across runs and long days on your feet. The shoe balances a plush underfoot experience with a precision-engineered upper made partly from Parley Ocean Plastic.

Key Features

• BOOST energy return: The fused energy capsules provide a responsive, springy ride that helps reduce fatigue on longer runs.
• ADIDAS PRIMEKNIT upper: The engineered knit conforms to the foot for a dynamic fit that moves with you while remaining breathable.
• Stretchweb with Continental Rubber outsole: The flexible Stretchweb design lets the sole flex naturally and the Continental Rubber offers improved traction on a variety of surfaces.
• Parley Ocean Plastic yarn: At least 50% of the upper yarn is reimagined ocean plastic, reducing waste and adding a sustainable element to the construction.
• Lightweight construction: The combination of knit upper and BOOST foam keeps overall weight low for everyday training and casual wear.

Who It's For

The Ultraboost 1.0 Sustain is best for runners and active walkers who want a cushioned, energizing ride and care about sustainable materials. It suits mixed-purpose use: daily training runs, long walks, and all-day wear where comfort and rebound matter.

Those who need a very wide toe box, aggressive slip resistance on wet surfaces, or a shoe that is extremely easy to pull on may want to try other silhouettes. Also, runners who depend on a very structured, motion-control platform should look elsewhere.

Pros & Cons

Pros

• Very high energy return from the BOOST midsole for an energized feel on push-off.
• Comfortable, adaptive fit from the ADIDAS PRIMEKNIT that hugs the foot while allowing movement.
• Eco-friendly upper with a minimum of 50% Parley Ocean Plastic in the yarn.
• Lightweight ride that works well for everyday running and casual wear.

Cons

• Some users report a narrow toe fit and occasional foot discomfort, so sizing and personal fit can be inconsistent.
• Reports of limited slip resistance in certain conditions suggest caution on wet or slick surfaces.
